Adobe will go to any lengths to avoid anyone from using any of their ‘ware for free or cheap. There are cheap or free equivalents for Photoshop, Illustrator, Indesign…
A former work colleague who taught me to use CorelDraw, Illustrator, QuarkXpress and Photoshop still pays a stupid amount of money every month to keep up an Adobe subscription because he’s still getting requests from people we did work for back in the 80’s-90’s to do updates on files, and the fonts and everything have to match perfectly, but he does use several apps on his iPad which have very similar functionality, and they’re available for MacOS as well. Certainly worth checking out and installing, for the kids development skills on DTP, vector and bitmap ‘ware are very transferable and well-worth building up.
